' BRICK-MACHINE..

SPEIFICATIGN forming part of Letters ratentfno. 283,366, dated August 21, ieee.

Application led VApril SJ, 1883. (No model.)y

'in connection with the accompanying draw'- ings, forming a part thereof, forms a full, clear, and exact description.

Referring to the drawings, Figure l is a side elevation of my improved machine as mounted on a dredging scow or boat. Fig. 2 is a plan mold-chain, showing the position of the scoops l or buckets during and after the molding opercember 12, 1882,- No. 268,976, and also for wet or pugged clay,where no great amount of press ure is required for pressing or shaping the brick into proper form. In the present instance, as in the patent above. referred to, the clayis dredged. or taken from the bed and molded into forni in one and the same operation without frequent handling of the clay,

thus reducing the cost of product-ion very materially, and furnishing a brick which will be amply sufficient for all ordinary building pur! poses.

To this end my invention consists of an endless'chain of moldswhich serve a twofold purpose-viz., molds in whi oh the bricks are given form, and also as `dredgingbuckets to receive the clay Afrom the cutting or dredging blades which form a part of the endless chain.

My invention consists, further, in attaching to the sides of the mold-chain a series of scoops or buckets,which are pivoted thereto in such a manner that they will fill the mold-cavity with clay, and then be made to tr( verse across the mold-cavity, so as to press the clay therein.

My invention consists, further, in placing underneath the mold-chain an endless chain Fig. 3 is a top view of a part of the of metal or other material, mounted on suitable pulleys and adapted to travel with the same velocity as the mold-chain, the said belt serving as a bottom for the molds.y

My invention consists, further, in certain details of construction, which will be fully described hereinafter, and pointed out in the claims.

Referring to the drawings, A designates a vessel of any suitable or desirable construction, on which I mount the operating parts of the machine. l do not limit myself, however, to the use of a vessel, as the mechanism may be mounted in a suitable structure near the claybank, where the clay can be tempered and scoops.

B and B are brackets or standards, secured firmly to the deck of the vessel or other structure, in which I mount the driving mechanism 'and the off-bearing mechanism for conveying the brick from the molding mechanism.

y C is the main supporting and driving shaft, to which power is applied in any suitable manner and from any convenient source. To the outer end of the shaft C are pivotally secured the plates D or frame of boiler-iron,

for supporting the excavating and molding mechanism.

E is a drum, rigidly secured to the outer end peripheral outline, to correspondwith thelinks of the mold-chain, and by means of which Vthe mold-chain is caused' to travel. rlhe drum E is also provided lwith plungeis, operated upon by 'cam-grooves, for ej ecting the brick from the mold onto the' off-bearing belt.

The lower end of the frame D is provided with a drum, F, of the same peripheral outline as the drum E, around` which the moldchain is caused to travel.

. To the axes ofthe drum Fis secured a bail, G, which in turn is secured to any suitable or convenient hoisting mechanism for raising or lowering the frame D. I

The portions of the machine which I have just described are essentially the same as the corresponding parts in the patent above reis deemed unnecessary Vat this time. The en dferred to, so that a further description of themplaced so as lto be fed to the mold-lling Y which constitute the sides of the frame-work of the shaft G, of octagonal or other form in lugs a, in which the excavating and mold-y filling scoops or buckets H are pivoted. The

p buckets or scoops H are made of steel castings,

to give them suitable` strength, and are provided with arms or projections b, cast thereon, and by which they are pivoted to the lugs c of the mold-chain. v f

To the arms b of the scoop are rigidly secured the bolts -or pivot-pins c, which are seated in the lugs a ofthe mold-boxes, and to the lower ends of the pivot-pins c are rigidly secured the arms c2, the outer ends of which are provided with friction-wheels c3. The lower inner edge of the scoops or buckets are beveled, as shown at c, Fig. 4, so that when the buckets are swept across the upper face ofthe mold the tendency will be to pack or compress the claysin the molds.

I is a cam-plate securely attached to the frame D, against which the friction-wheel of the arm c2 impinges as the( mold-chain is being carried up, which forces the arm c2 outward, and at the same time it carries with it the scoops or buckets II,A which describe a` quarter-circle in their passage across the moldcavities, sweeping off the surplus clay, and

pressing or compacting the clay which remains therein into brickform.

A cam or incline, J, is secured to the lower edge of the frame D, for the purpose of moving the scoops or buckets back across the face of the mold-chain and into a position where they will act on the clay to excavate the same.

The incline or cam J is provided with a groove `which converges toward the frame D, in which the friction-wheels o3 enter, and thus force the arm c2 toward the frame D, and the scoops H back against the studs or projections a2, which are cast -on the mold-sections, and which support and steady the outer end of the scoops or f buckets. Other equivalent devices may be used for operating the scoops without departing fronrthe spirit of my invention.

K is an endless belt of metal or other material mounted on the pulley-wheels L L, which form the bottom of the mold-boxes between the point Aat which the brick is formed and the ward by the mold-chain, or by any suitable mechanism, at the same velocity or rate of spee d as the mold-chain, so as to prevent any drag up- .on the under side of the newly-formed brick,

while`friction-rol1s m, secured in the frame D, serve to steady and support the endless belt and keep it snug against the under side of the molds. A flooring or solid portion isplaced on the upper side of the frame D atl a point between the drum F and the lower pulley, L, of the endless belt, so as to prevent the clay from falling through the molds before reaching the endless belt.

The operation of mydevice is as follows: Motion is imparted to the endless chain of molds and scoops, the scoops enter the clay and are vfilled as they are drawn up and assume a vertical position, and the clay is 'discharged therefrom into themolds by the force of gravity.

The projecting arms which operate the scoops or buckets now come in contact with a cam or incline, I, which forces them out and causes the scoops H to traverse across the face of the mold, sweeping off any surplus clay and forcing enough in the mold-cavity toform abrick. The bricks thus formed are c arried up over the drum E, where they are ejected from the molds to the off-bearing belt. The scoops or buckets remain in this outward position until they near the lower drum, F, where, by means of the cam -plate J, they are thrown back across the face ofthe mold-chain and into position for taking up another load of clay and dumping it into the mold.

I do notwish to limit myself by the forego-l ing description to an endless chain of open molds, for it is obvious that the molds maybe provided with movablebottoms confined therein in such a manner as to admit of their being' ISM 1. `A brick making'or molding machine-consisting of a series or endless chain of molds roo having pivoted thereto scoops or buckets for p raising the clay and as set fort-h.

2. In a brick making or molding machine, a series or endless chain of traveling molds placing it in the molds,

` provided with excavating or filling scoops pivoted thereto, and means, substantially such as described, for swinging said scoops over the face of the mold, to press the clay therein and remove the surplus clay therefrom, as set forth.

3. In a machine for molding plastic material into shape, a series or endless chain-of molds or formers having attached thereto excavating and filling scoops or buckets, which are pivoted thereto and adapted to be moved across j the face of the mold, as and for the purpose top drum, E. This endless belt is carried for-A set forth.

4. A brick making or molding machine consisting of a series or endless chain of connected molds having pivoted thereto filling scoops or buckets, substantially such as described, and
